How is a synthesis reaction different from a decomposition reaction (use your notes)?
Q Of The Day Day 6 5-9
Types of Chemical EquationsDouble-replacement ReactionsDouble-replacement reactions – the ions of 2 cmpds. exchange places in an aqueous sltn. to form 2 new cmpds.
AX + BY AY + BX
A, B, X, and Y = ions
Example:
2KI(aq) + Pb(NO3)2(aq) PbI2(s) + 2KNO3(aq)
AX BY BX AY

How does the Law of Conservation of Matter apply to chemical reactions?
How do substances react to form products?
Types of Chemical EquationsCombustion ReactionsCombustion reactions – a substance combines with oxygen, releasing a large amount of energy (light or heat)
Unique equations
Examples:
Hydrogen gas: 2H2(g) + O2(g) 2H2O(g)
Propane: C3H8(g) + 5O2(g) 3CO2(g) + 4H2O(g)
